I havent followed the subject of the deep dungeon they are creating, but do we know if they have decided to design it with solo play in mind?

PotD might be soloable but not only does it require a long grind with hopes of getting lucky, it often feels terrible solo because the content was never designed with solo players in mind, going on an unlucky rng floor or instant death auto attack is death while for a group it isnt. Let's not even mention the fact melee have to try break npc auto attacks with spinning to even survive...
Havent checked out HoH because from what i understood it is quite similar.

One thing WoW did better in terms of deep dungeon was their torghast dungeon which was designed to be done solo rather than group, groups could do it but solo players could do it as well so it was never about getting lucky or having really bad floors, you could always find a way to beat the floor even slowly.

Do we know if the new deep dungeon gonna be designed with solo players in mind or going to be the same as PotD?
